With HTC just having announced its One-series of Androids, some of the remaining details on the phones are starting to fall into place, along with those for the One XL, which we heard mentioned earlier this month.

Retailers are expecting the global version of the quad-core HTC One X to become available early in April  Clove is listing April 5 for both the One X and One S  and should cost somewhere around $650 before taxes, which sounds quite reasonable for its high-end hardware.

All official specs we’ve seen for the global One X have it with a quad-band 850/900/1900/2100MHz radio, but we’ve also heard claims that the handset will run on the 1700MHz AWS band, as well.

The One S should be finding a home with T-Mobile in the States, though we’re not sure just when that will be. Internationally, it’s expected for early April, like the One X, and should be a bit more affordable at around $590. Frequency support looks slightly worse than the One X, with no 1900MHz 3G.

It looks like the One V will arrive a little after the X and S, expected for closer to the end of the month. Clove plans to have the phone to sell for April 26, fetching the equivalent of about $350.

When we first heard the name One XL, we wondered if it would be some kind of jumbo-sized model, but now it’s apparent that the XL is a slightly-downgraded version of the X, but with LTE support. To that end, it scales-back the processor to a dual-core 1.5GHz component, like the One S.

In fact, the hardware specs of the XL line-up quite nicely with those of the S. The only functional differences we’ve noticed are the lack of LTE and NFC on the One S. The XL should be coming to AT&T sometime this April.
